1 General information
1.1 Concerning the contents of this document
This manual contains information about the installation and commissioning of the ipf light section sensors
PY740020 and PY740021.
It is a supplement to the mounting instructions supplied with each sensor.
1.2 Intended use
The PY740020/21 sensor detects edges and outputs their position, distance, and center between edges.
It was especially developed for easy handling, flexible use, and precise measurement. The red light laser
ensures that the light beam is always visible, which makes sensor alignment easier and minimizes installation
errors. The sensor operates without a reflector.
1.3 Comments, notes and warnings
ATTENTION!
Indicates a possibly hazardous situation. If it is not avoided, minor or slight injuries
can occur or the device can be damaged.
Read these operating instructions carefully and follow the safety instructions!
NOTE
Provides helpful operation instructions or other general recommendations.

2 Commissioning in 4 steps
After the sensor is connected and installed, configure it via the display, selecting either the "Edge", "Width" or
"Gap" function and performing the other application-specific settings/measurement type within these
functions. The sensor is then ready for operation and outputs the measuring value in mm to the screen.
Optionally, the measuring field can be limited or the switching output can be configured.

2.2 Mounting
Standard installation
In standard installation, the sensor is mounted at a
right angle to the reference surface or the object. The
sensor is not taught into the reference surface so
configuration is very easy and straightforward.
This installation method is recommended even if the
reference surface cannot be taught in for some
reason or another.
Angled installation
In angled installation, the sensor can be mounted
at an angle of up to +/-
30° in relation to the
reference surface. This installation method is used
when space
conditions do not allow any other
installation option or the mounting angle is not
known.
Align the sensor as accurately as possible at a right
angle to the reference surface (background) or to the
object (if there is no reference surface in the
measuring field). The object must be within the
measuring field, i.e. the distance from the sensor
must be between the start of the measuring range
Sdc and the end of the measuring range Sde.
The sensor may be mounted at an angle inclined
maximally 30° to the left or to the right of the
reference surface (background) or to the object (if
there is no reference surface in the measuring
field).
Reference surface (background) and object must
be within the measuring field.
NOTE
The "Edge L rise or Edge R rise" mode can be used as an aid to find the zero point.
Now an object is slowly pushed toward the presumed zero point. The zero point is
reached by the rising edge of the object when the value 0 mm is shown on the sensor
display and the yellow LED switches.

2.1 Optional settings
Let’s get started
The sensor continously displays the
measured value in mm on the display and
transmits it via analog output to the PLC.
Measuring field limitation (optional)
The measuring field can be changed via the
MEASURING FIELD function. This function
is required when there are objects in the
measuring field which should not be
detected.
- AUTO for limitation with a rectangle
of automatic size
- Separate configuration of the single
points of the field

Switching output (optional)
The sensor has a switching output that can
be configured as threshold or window via the
function DIGITAL OUT.

3 Connection
3.1 Connection cable
You need an 8-pin, shielded connection cable (cable socket).
We recommend the ipf connection cables with the following article numbers:
•VK205A21/25 (Length 2m, M12 socket angular/straight)
•VK505A21/25 (Length 5m, M12 socket angular/straight)
•VKA05A21/25 (Length 10m, M12 socket angular/straight)
Other cable lengths are available.
When the analog output is used, the cable length affects signal noise. Signal noise increases the longer the
connection cable is.
Analog output I_OUT
Noise: 5.92 µA (1 sigma) (10m cable and 680 Ohm)
3.59 µA (1 sigma) (2m cable and 680 Ohm)
Analog output U_OUT
Noise: 4.80 mV (1 sigma) (10m cable and 100 kOhm)
3.03 mV (1 sigma) (2m cable and 100 kOhm)
ATTENTION!
Laser class 1 laser beam according to EN 60825-1:2014. This product can be
operated safely without any additional safety precautions. Nevertheless direct
contact between the eye and beam should be avoided.
ATTENTION!
The IP protection class is valid only if all connections are connected as
described in the technical documentation.
ATTENTION!
Connection, installation and commissioning may only be performed by qualified
personnel.
ATTENTION!
Incorrect supply voltage will destroy the device!

4 Installation
4.1 Mounting
The sensor has four mounting holes for flexible alignment and mounting. The use of 2 M4x35 screws is
recommended for mounting. The tightening torque is max. 1.2Nm.
4.2 Sensor reference levels
To ensure easy alignment of the sensor during installation, the surfaces defined here are available:
The laser beam of the sensor runs parallel ( // ) to level R3 and is at a right angle to levels R1 and R2. Levels
R1, R2, and R3 serve as a reference for sensor alignment during installation. "Left" and "Right" designations
are also important.

4.3 The reference surface
The measuring level where the object to be detected is located is referred to as the reference surface. It
should be as even as possible; there must not be any edges in the measuring field which should not be
detected (for exceptions see chapter MEASURING FIELD).
If there is no reference surface as a measuring level, the sensor should be aligned to the object.
If the PY74 sensor cannot be aligned at a right angle to the reference surface, the FLEX MOUNT function
should be activated.

4.4 Sensor alignment
As standard the sensor is mounted at a right angle (90°) to the reference surface or the object (standard
installation), but it can also be mounted at an angle of up to 30° (angled installation).
To get the most accurate measurements possible in angled installation, the inclination angle of the sensor has
to be taught in, see chapter FLEX MOUNT.
The distance from the reference surface or the object must not exceed the "End of measuring range" value on
the measuring axis.
Note
Angle deviations can affect measuring accuracy (see chapter Alignment errors).
Tip
To facilitate sensor alignment, LIVE MONITOR can be used as an aid. LIVE
MONITOR continuously outputs the currently measured angle and the distance
from the reference surface.

4.5.2 Blind area
The area up to the start of measuring range Sdc is called the blind area, i.e. the sensor cannot detect any
objects there.
Nevertheless, placing an object there should be avoided since the resulting shadowing of objects could
produce incorrect measuring values.
4.6 Angled installation
Compared to standard installation, the sensor can be mounted at an arbitrary inclination angle up to ±30°.
This is particularly useful when space conditions do not allow any other installation option. See Section FLEX
MOUNT.
The object must be within the measuring field.

4.6.1 Definition of the measuring field with angled installation
At the maximum allowable inclination angle of ±30°, the sensor measures objects and edges within the
measuring field defined below. The important terms "left" and "right" are to be regarded respectively from the
viewpoint of the sensor, and in the following figures from the viewpoint of the connector side of the sensor.
After activation of the FLEX MOUNT function, the sensor axis is no longer relevant. The measurement
coordinate system is now represented by the M and K axes. The measurement value is now the distance on
an edge to the M axis.

4.7 Practical zero point search
In case of angled installation, the zero point (0mm) oft he K axis shifts out of the center of the red visible laser
line.
4.8 Installation accessories
To ensure optimal mounting, the mounting bracket AP000043 is available as an accessory. This bracket fits
best with the ball-head holder AY000143.
The sensor can be aligned within the entire pivoting radius of the ball-head.
4.8.1 Mounting kit for PY74 series
With the mounting bracket AP000043 and the ball-head AY000143 the sensor can be mounted quickly and
easily in any orientation.
NOTE
The "Edge L rise or Edge R rise" mode, for example, can be used as an aid to find
the zero point. Now an object is slowly pushed toward the presumed zero point.
The zero point is reached by the left rising edge of the object when the value 0 mm
is shown on the sensor display and the yellow LED switches.
